No problem. BTW, I assume you have checked that the 50 MHz is actually OK, meaning that the VCO, divider (U74) and driver (Q72) are working (so 50 MHz is getting to U75 pin 1). Correct?

Caesar I have both IDE-IDE and USB-IDE adapters for the 2.5" PATA drive. For whatever reasons I didn't have much luck cloning the 40GB you gave me. At this point the unit is fully back together and

Hi Mark, Thanks a bunch for the info. That gives me a more stuff to check. Cheers, Mike From: <[email protected]> on behalf of "Mark Bielman via Groups.Io"

Do you remember what Linux flavor and rev you used? I have used Linux sparingly over the years and always found it to be very unforgiving for many of the MBs I have tried to use maybe 10 different

Bill I had that but that only answers half the question . The 5308A is NOT listed in the 5300A manual but that may only mean that the 5308A came out AFTGER the the publishing of my 5300A manual as an

Hello again Michael, Looking at the CLIP now and see that the E4401 is indeed different from others. (800 MHz VCO, divided by 16) So assume that the H_CAL_OSC_ON is not active. Correct? (active high

I’m not sure about the 0 Hz feedthrough – I’m at work presently. I’ll have some bench time tonight. I understand about your earlier comment regarding probe loading. I do not have an active

do you have the LO feedthrough at 0Hz?

I understand that. As I stated in my earlier postings, the issue is that the internal 50 Cal signal is not functioning, which is what I am trying to fix. From:

The 70590A is useless, except you have the military softwares from Air Force or Navy dedicated to some gear (F18...) but they need a lot of non HP plug ins (Comstron, Tern Technology...) under ITAR

Can the 5300A and 5300B display units be used interchangeably with all the 53xxA and 53xxB counters and DMM's? (i.e say a 5308A counter and a 5300B display as an example or vice versa Dave

Hi I have spoken to the UK supplier I am due to visit him this week but I don’t think he believed me when I told him I had only found 7 independent users of HP 70000 equipment in the UK and that a

Dave,? Got side tracked.? ?Have about 75% finished.? ?Within the next few days I should have it finished.? Going to be 2-3 parts each around an hour each.? Much detail presented. George

Does anyone still use MATE? I worked on a runner up to that program a long while ago... ("our" proposal wasn't accepted).... Did some 488 bus programming using a TMS9914 controller run by an 8088.

Hi Paul, "The HP 70590A Options H69 and H72 TMAs (Test Module Adapters) are MATE modules for HP 70000 Series spectrum analyzers. The modules translate CIIL (control intermediate interface language)

I think the cal signal on that unit is built into the unit. You do not have to connect an external cable to calibrate. Please check the manual.

George, I am looking forward to your video on the design of a modern DMM. ?Do you possibly have an update? Cheers, David

The lack of detent and friction are not related to o-rings. Take off the end-cap (4 socket screws). This will allow you to slide off the u-shaped cover. You will see a camshaft held by two bushings

Is the 4401 really that different from the '02, '03, etc? Have never looked at an '01.
